It was not always the Desert

The great Sahara Desert was once a lush green land. This Fact may surprise most of you but it is completely true. It has changed drastically in the past years. This change came approximately 5000 years ago. It was a result of the change in the earth axis. Years ago the Earth’s axis was tilted in such a way that Nothern Hemisphere was closer to the sun. This tilted Nothern Hemisphere resulted in Monsoon Rains in this region. Thus it was completely habitable and used to have rich Flora and Fauna. Now, years later the northern hemisphere is about a degree away from Sun. Statistically speaking before it was 24.5 degrees and now it is 23.5 degrees. It is expected that the great Sahara will be green again after some thousands of years.
